Pass RSS link & data to another page

Im new to coding in WordPress. Anyone know of any links (or any plugins) where I can read up on how to pass data from one page to another.

I’m using Show_RSS to display a list of links on the Front Page, and when the user clicks the link I want to display the article summary on another page, rather than going off-site to the source page.

I’ve trawled Wp & Google. So far using a session var seems to be a better way than a global var. But I’m not sure how to process the link.
